“TRANSFORMER: The Deep Chemistry of Life and Death” By Nick Lane
A Theory of Life Told Through the Flow of Matter
At this very moment, inside our bodies, roughly a billion molecular changes are occurring every second within each individual cell. The key concept biochemist Nick Lane builds this book around, "flux," is not simply a flow. It is a circuit in which matter continuously transforms as it passes through. Imagine Volkswagen Beetles streaming into a street every second, each one blazing with light as it morphs in turn into a Porsche, a Volvo, a tractor, before exiting the other end — to borrow the author's own metaphor, countless such strange metabolic thoroughfares run through our bodies. Against the mainstream of modern biology, which seeks to explain life through genetic information, this book proposes a different vantage point: understanding life through the flow of energy and matter. Following the argument requires patience to picture the workings of complex molecules, but it isn't necessary to grasp everything. If you reach the moments when the author's insight breaks through like light between storm clouds, the effort will have been amply rewarded. What struck me most was the observation that the Krebs cycle — the linchpin that generates ATP, life's universal energy currency — once functioned in exactly the opposite direction in ancient bacteria: it was a biosynthetic engine that assembled carbon dioxide into organic molecules. A revolution occurred at the very foundation of life. Around two billion years ago, a planet-wide shift called the Great Oxidation Event (GOE) ushered in a world with sharply higher oxygen levels, and life survived by running that same cycle in reverse. The book's reflections on cancer are also thought-provoking. Cancer cells suppress ATP production and switch instead toward growth itself — an image that seems to mirror our own society's pursuit of endless growth. Meanwhile, the observation that even the simplest cells maintain boundaries of "self," sustained by a ceaseless flow of energy, forces a fundamental rethinking of what it means to know oneself. "A cell is a miniature battery that recreates the Earth." Reading that line, I found myself struck by the realization that my own body still carries, within it, evidence of its origins in this planet. By tracing the roots of life back to the flow of matter, this book unsettles the very boundaries of what we take ourselves to be. Our lives are set in motion by a flow far too vast to ever fully imagine. Translated by Takao Saito. (¥3,960)
